Summary
The Factor Ostro is an aero-focused gravel race bike designed for speed and performance on smooth terrain. It excels in stiffness, aerodynamics, and handling, making it a top choice for racing and fast rides. However, it sacrifices comfort and versatility, with a firm ride that can be harsh on rough surfaces and limited utility for diverse conditions.

Superior handling on smooth terrain
Lightweight construction
Premium componentry and build quality
Firm and uncomfortable ride, especially on rough terrain

developed to dominate its category with incredible aero, superior handling, high stiffness and low weight
On smooth, well-graded gravel it is like being shot out of a cannon.
It’s a gravel bike for race day, designed with winning in mind through and through.
